# Template Magic for Quanta:
|
|
|
# This script is intended to be used as a sample of some of the possibilities of integrating
|
|
|
# Kommander and Quanta. It's hoped that this can serve as a basic example of how Kommander works
|
|
|
# and how it can speed you're web development.
|
|
|
#
|
|
|
# This script exists in the public domain and may be freely copied and redistributed. Please just
|
|
|
# let me know that you used my script and what you're doing (I like new ideas).
|
|
|
#
|
|
|
# As usual, if this script by some means manages to do any harm to you, your computer, your animal,
|
|
|
# your relatives or your animal relatives, feel free to vent to me in email and I'll try to fix the
|
|
|
# script. You'll have to take care of the livestock.
|
|
|
#
|
|
|
# Template variables are of the form [ varname:vartype ] where vartype can be either
|
|
|
# 'file', 'filename' or 'text'. Filename and file are two slight variations on the same theme
|
|
|
# as both allow you to select a file from your filesystem, file will insert the contents of that
|
|
|
# file whereas filename will simply insert the filename (with the path). Text is simply a rich
|
|
|
# text field that can take a good little bit of text (the limitation if any will exist in
|
|
|
# Kommander or your computers memory).
